Case Study on the Moving of Patients Using Blockchains’ Federation

He patients moving between medical institutions is a process that takes place on a daily basis, either to continue or improve their treatment. At each moment of the moving (origin hospital, means of transport and destination hospital) information is generated in isolation, which is recorded in each of the health information systems. This limits the interoperability needed to provide quality services to the patient. Also, it is not possible to have the trajectory of the information when a patient is moved, generating problems in medical decision making, since only a small vision of the actors in each system is available. In this paper, a case study of patients moving between medical institutions is presented, applying the FedBlocks tool, which uses the concept of Blockchain federation, where a higher order Blockchain is in charge of federating a set of lower level Blockchains, generating a view of the patient’s entire medical history. Likewise, all interconnected systems communicate and can share authorized data of their patients, providing a benefit for these systems and for the actors of the entire ecosystem.
